IMAGE DISPLAY DEVICE AND IMAGE DISPLAY METHOD

摘要

Provided is an image display device and an image display method, in which a rotation change of the cutout images each including the moving object is suppressed when the omnidirectional camera tracks the moving object that passes nearly under the omnidirectional camera, and also the cutout images flips vertically when the moving object passes under the omnidirectional camera, whereby easily viewable image display is always enabled. A subsequent position is predicted based on a current position of the moving object, and coordinates of the predicted moving position are transformed into coordinates on a real space plane, and a rotating speed in the image direction is calculated based on the coordinates on the real space plane. If a highest rotating speed of the calculated rotating speeds is equal to or larger than a given threshold value, a cutout parameter for setting the upward direction of the cutout images is corrected, and the images including the moving object are cut out of the omnidirectional image using the corrected cutout parameter, and displayed. In other words, the rotating speed is adjusted when the images including the moving object are cut out of the omnidirectional image.
